When a procurement officer or Combat Engineer sits down to write a temporary infrastructure brief for a forward operating base, a police tactical operations centre, or an EOD compound, the checklist tends to look the same. Ground bearing capacity. Panel load ratings. Deployment timelines. Environmental conditions.
These are the right questions. They are also not the only questions.
In an increasing range of operational environments — from NATO forward positions to peacekeeping zones, from high-risk policing operations to humanitarian missions in conflict-adjacent regions — the brief should also ask: what happens if the threat isn’t structural? What happens when the risk isn’t the ground giving way, but fragmentation, blast pressure, or ballistic impact?
This article sets out what a complete defence infrastructure brief should include when ballistic and fragmentation protection is a live concern, and why this capability remains, despite its importance, almost entirely absent from mainstream temporary infrastructure provision.
Why fragmentation protection belongs in the infrastructure brief
Ballistic and fragmentation risk is not confined to the front line. The environments where temporary infrastructure is deployed most heavily — staging areas, equipment compounds, command posts, medical triage points, and personnel accommodation — are precisely the environments where protection requirements are most likely to be underspecified.
Fragmentation from IEDs, indirect fire, and secondary blast effects travels indiscriminately. It does not respect the boundary between a tactical asset and a logistics asset. A vehicle compound with no hardening, a generator station with no blast attenuation, or a personnel rest area with no fragmentation barrier represents a vulnerability that no amount of structural engineering can compensate for.
The cases are not theoretical. Post-incident analysis from multiple operational theatres has consistently shown that fragmentation casualties in support and staging areas are disproportionately high relative to the perceived risk at the time of deployment. Infrastructure planners have a direct role in reducing that exposure.
1. Forward Operating Bases and Patrol Bases
At FOBs and PBs, the temporary infrastructure estate typically includes accommodation, command and communications, medical, and logistics functions. Each of these carries different fragmentation risk profiles. Personnel accommodation requires both blast mitigation and fragmentation containment. Command nodes require protection against targeted attack. Medical facilities require the highest possible protection levels given their role and the vulnerability of their occupants.
A well-specified brief for FOB infrastructure will define protection levels against fragmentation, specify standoff distances for blast mitigation, and identify which structures require hardened perimeter solutions as distinct from general field engineering.
2. Police Tactical Operations and Firearms Units
High-risk policing environments — including counter-terrorism operations, armed response cordons, and EOD support — increasingly require temporary infrastructure that can provide ballistic protection for personnel staging areas. This is distinct from the permanent architecture of police buildings and reflects the need to establish hardened positions in unpredictable locations at short notice.
Fragmentation protection in these contexts typically centres on personnel shelters, command vehicle surrounds, and forward equipment stores. The capability requirement is real; the infrastructure provision has historically lagged behind it.
3. EOD and CBRN Operations
Explosive Ordnance Disposal and CBRN response operations involve the closest sustained proximity to fragmentation risk of any non-combat function. The temporary infrastructure supporting these operations — holding areas, equipment staging, decontamination zones — requires protection against secondary blast and fragmentation as a baseline, not an enhancement.
EOD briefs that omit fragmentation protection specifications are not simply incomplete. They represent a gap in the duty of care owed to the operators working within those environments.
4. Humanitarian Operations in Volatile Environments
The humanitarian sector has historically been slow to engage with ballistic protection requirements, partly for reasons of optics and partly because the capability has not been readily available in civilian supply chains. This is changing. Operations in conflict-adjacent environments, post-conflict zones, and areas of civil unrest increasingly require infrastructure that can protect personnel and assets without the footprint or permanence of military field engineering.
Modular, deployable fragmentation protection that can be installed and removed without specialist equipment is not a niche capability. It is a gap in humanitarian infrastructure provision that carries direct consequences for personnel safety.
What a complete ballistic and fragmentation protection specification looks like
A properly specified infrastructure brief for any of the above environments should address the following:
Protection level classification. Not all ballistic protection is equivalent. The brief should define the required protection level against fragmentation (typically referenced against STANAG 4569 or equivalent national standards), the threat types to be mitigated, and the acceptable residual risk level. Vague references to “blast protection” or “fragmentation mitigation” without calibration to a recognised standard are not specifications — they are placeholders.
Structural integration with temporary infrastructure. Ballistic protection that cannot be integrated with the surrounding infrastructure estate creates as many problems as it solves. The brief should specify how fragmentation barriers, blast walls, and hardened panels interface with flooring, access routes, and superstructure. Modular systems that connect directly to the ground protection and flooring substrate reduce complexity and deployment time.
Perimeter hardening versus point protection. These are distinct requirements. Perimeter hardening addresses the threat at the boundary of a site or compound. Point protection addresses the threat at specific assets — a command post, a medical station, a generator. A complete brief distinguishes between the two and specifies both where required.
Deployment and recovery. In temporary infrastructure, the deployment and recovery timeline is not a secondary consideration. Hardened solutions that require specialist plant, significant groundwork, or extended installation are not suitable for forward positions or rapidly evolving operational environments. The brief should specify maximum deployment time, required personnel, and recovery requirements as part of the protection specification.
Integration with ground protection. In environments where ground conditions are a primary constraint — soft ground, seasonal flooding, post-blast terrain disruption — the relationship between ballistic protection and ground bearing capacity becomes directly relevant. Heavy blast walls on unprepared ground create secondary risks. The brief should address how ballistic protection loads are distributed and whether ground protection is required as a precondition.
Why this capability is rare in the UK temporary infrastructure market
The UK temporary infrastructure market is well-developed in conventional terms. Ground protection, modular flooring, trackway, and temporary roadway solutions are widely available from multiple suppliers. Ballistic and fragmentation protection, by contrast, is almost entirely absent from the civilian temporary infrastructure supply chain.
This is partly a function of market structure. Most temporary infrastructure suppliers in the UK serve the events, construction, and utilities sectors, where ballistic protection is not a requirement. The capability required for military and high-risk policing applications sits in a different part of the market — specialist defence suppliers — and is typically delivered as a permanent or semi-permanent solution rather than as temporary, modular infrastructure.
The gap this creates is real and consequential. Procurement officers working on deployable infrastructure requirements either have to source ballistic protection separately from a specialist supplier — creating integration challenges — or specify around the gap, accepting a lower protection standard than the environment warrants.
The Box Group operates in this gap deliberately. Our capability set spans both the conventional temporary infrastructure requirements — ground protection, access flooring, trackway, modular buildings — and ballistic and fragmentation protection solutions designed to integrate with that estate. This is not a common combination. In the UK temporary infrastructure market, it is close to unique.
What to specify: a practical checklist for planners
For procurement officers and infrastructure planners working on briefs where ballistic and fragmentation protection is a consideration, the following checklist provides a starting framework:
- Define the threat environment: indirect fire, IED fragmentation, direct fire, secondary blast
- Reference the applicable protection standard (STANAG 4569, VPAM, or national equivalent)
- Identify which areas of the infrastructure estate require hardened protection (all areas vs. specific nodes)
- Specify perimeter hardening requirements separately from point protection requirements
- Define maximum deployment and recovery timelines
Confirm ground bearing capacity and ground protection requirements for protection system loads - Specify integration requirements with surrounding infrastructure (flooring, access, superstructure)
- Confirm logistics constraints: transport footprint, handling equipment, storage requirements
- Define inspection and maintenance requirements in-theatre
A brief that addresses each of these points will produce a specification that is both operationally credible and practically deliverable. A brief that omits them will produce a solution that looks complete on paper and is not complete in the field.
Ballistic and fragmentation protection is not a specialist add-on to temporary infrastructure. In a growing range of operational environments, it is a core requirement — one that belongs in the initial brief alongside ground bearing capacity and deployment timelines, not in a post-incident review.
The infrastructure community has the technical capability to meet this requirement. What has been missing, in many cases, is the supplier with both the temporary infrastructure expertise and the ballistic protection capability to deliver a fully integrated solution.
That is the position The Box Group occupies. If your next infrastructure brief includes a protection requirement, we would welcome the conversation.
